Marines to get upto 904 new CRRCs, which is way more than they ‘should’ need

From DOD: 

Wing Inflatables Inc., Arcata, California, is awarded a $31,921,100 firm-fixed-price, indefinite-delivery/indefinite-quantity contract for the purchase of up to a maximum 904 Enhanced – Combat Rubber Reconnaissance Craft. Work will be performed in Arcata, California, and is expected to be complete by August 2026. Fiscal 2019 and 2022 procurement (Marine Corps) contract funds in the amount of $3,126,894 will be obligated on the first delivery order immediately following contract award and funds will expire the end of the fiscal 2022 and 2023, respectively. This contract was competitively procured via the System for Award Management website, with three proposals received. The Marine Corps Systems Command, Quantico, Virginia, is the contracting activity (M67854-21-D-1801).

Wing’s five-chamber P4.7 series inflatable runs 15′ 5″-feet long, has a 6′ 5″-foot beam, offers 38.32ft² of usable deck space on a 12×3-foot deck. Empty weight is 180-pounds not counting the 274-pound rollup hard deck insert and can accommodate a 65hp outboard and 10 passengers/2,768-pounds of payload. The whole thing folds up into a 27″x29″x56″ package, or roughly the size of a curbside garbage can.

Each of the 7 Marine Expeditionary Units (a battalion landing team with a bunch of stuff bolted onto it and a harrier/helicopter airwing for support) has a bunch of different ways to get to the beach. These include of course the choppers, navy landing craft (LCU, LCAC, etc), and the Marines own amtrac swimming APCs. However, each one of these MAUs also has 18 of these little rubber zodiac-style boats, designated Combat Rubber Raiding Craft (CRRC, or “Crick”).

A little larger than a sectional couch and powered by an outboard (or two) these can motor out from a task force still some 20 miles out at sea and approach an enemy-held beach, port, or vessel with very little footprint. They are hard to spot by eyeball, radar, or other means, especially in a light chop state. It’s a wet ride for the Marines aboard and anyone who has ever ridden one through the surf doesn’t look forward to doing it a second time– especially on a contested beach.

For landings, a company of the battalion landing team is designated the “Boat Company” and they spend a couple weeks figuring these boats out. This includes sending as many as 36 of its force before deployment through a four-week coxswains school where they learn basic sea-nav, and what not to do with these temperamental crafts. Meanwhile, other members of the Boat Coy head off to scout swimmer school where they learn the finer points of exiting a rubber raft on fins and doing lite frogman shit.

In the end, Cricks allow a 144-man company to be landed on a strip of beach or empty pier in three, six-boat waves. The former was done under OOTW conditions by Marines in Somalia in 1992.

Air transportable, Cricks can be slid out the rear ramp of MV-22s or parachuted from cargo planes such as the C-130 (and Navy C-2 CODs), can be launched from surface vessels such ranging from Amphibious assault ships (shown) or smaller craft like patrol boats, LCS and frigates. They can also be (and are) carried up from submerged submarines by divers for inflation on the surface.

The thing is, if you do the basic math on 7 MEU boat companies x 18 E-CRRCs, you get just 126 boats. Even if you double that amount to cover training and attrition, then add some for SEAL ops from submarines and for the use of Force Recon/Raider units, you still have like ~500 extra small boats.

That’s an interesting thing to ponder. 

I’d like to mention that a few months back, I theorized that the Marines might use Cricks to displace human assets from anti-ship missile batteries after they have fired their missiles from isolated atolls before the Chinese show up in force. Fire off their NSSMs, drop some WP grenades on their trucks, hop in the inflatables, and meet with a passing SSN or EPF just past the 15-fathom curve. May be easier to accomplish and have less of a footprint than an MV-22 pickup. 

Rig for divers

COMSUBPAC recently released several images of things you don’t usually see: Dry Deck Shelter and submerged diver operations on a Virginia-class hunter-killer submarine.

The Navy only has about a half-dozen of the 38-foot DDSs (2-3 in each of the SDV Teams), which were put into service in the 1980s to replace the capability lost when the Pentagon scrapped the old transport submarines (see USS Perch) of the Vietnam-era. Boats such as Perch could put ashore platoon-sized elements of Marines or UDTs/SEALs via small boats and do so in relatively (for the blue water Navy) shallow water.

While usually older boats operate DDSs– for instance converted Tridents turned into SSGNs– 10 of Virginias are believed equipped to operate DDSs, which can support a SEAL platoon (16 operators) for dive or small boat (CRRC) operations.

Previous to these images, some of the last good quality released images of DDS shelters in use on DVIDS date to earlier this year and, beyond that to 2008, both on converted SSGNs.

Ohio CRRCs

The Navy has recently released a sizzle reel and some additional images of the exercise earlier this month of Force Recon Marines and their combat rubber raiding craft (CRRCs) on the converted boomer USS Ohio (SSGN 726) off Okinawa.

Notably, there are some rare detailed shots of Ohio’s lockout chamber, converted Trident SLBM tubes, being used to store the CRRCs and their outboards.

 

Sub-Marine ops, Back In style

The Marines have been rubber boating around, a skill they are used to as each Battalion Landing Team for years has typically included a designated “Boat Company,” trained to run about on 15-foot Combat Rubber Raiding Craft (CRRC, or “Crick”).

What is interesting about this is that they recently did so in conjunction with a converted boomer in the Philippine Sea, embarking on some expeditionary training. The standard Dry Deck Shelters used by the Navy’s submarines are each able to carry an SDV minisub for use by SEALs– or four CRRCs, enough to carry a platoon-size Marine maritime raid force.

PHILIPPINE SEA (Feb. 2, 2021) The Ohio-class guided-missile submarine USS Ohio (SSGN 726), deployed to the U.S. 7th Fleet area of operations, rendezvous with a combat rubber raiding craft, attached to U.S. Marine Corps Force Reconnaissance Company, III Marine Expedition Force (MEF), for an integration exercise off the coast of Okinawa, Japan. The exercise was part of ongoing III MEF-U.S. 7th Fleet efforts to provide flexible, forward-postured, and quick response-options to regional commanders. (U.S. Marine Corps photo by Sgt. Audrey M. C. Rampton)

“This training demonstrates the ability of Force Reconnaissance Marines in III MEF to operate with strategic U.S. Navy assets,” said III MEF Force Reconnaissance Company Commanding Officer Maj. Daniel Romans. “As the stand-in force in the first island chain, it is critical that Force Reconnaissance Marines are capable of being employed across a myriad of U.S. Navy platforms in order to enhance the lethality of the fleet in the littoral environment. Reconnaissance Marines have a proud history of working with submarines and we look forward to sustaining these relationships in the future.”

It is not a dramatically new concept.

On 17 August 1942, just nine months after Pearl Harbor, 211 Marines of the 2nd Marine Raider Battalion embarked aboard the submarines USS Argonaut and Nautilus crept ashore at Makin Island and did what the Raiders were meant to do– hit hard in the most unexpected area they could find and jack up a small Japanese garrison.

Then of course, throughout the 1950s and 60s, Marines on submarines were a regular sight…

Warship Wednesday, Oct. 25, 2017: Putting the ‘Marine’ back in submarine

Here at LSOZI, we are going to take off every Wednesday for a look at the old steam/diesel navies of the 1859-1946 time period and will profile a different ship (in this case, doctrine) each week. These ships have a life, a tale all of their own, which sometimes takes them to the strangest places. – Christopher Eger

Warship Wednesday, Oct. 25, 2017: Putting the ‘Marine’ back in the submarine

Yes, Dolphins on a Marine uniform…

On 17 August 1942, just nine months after Pearl Harbor, 211 Marines of the 2nd Marine Raider Battalion embarked aboard the submarines USS Argonaut and Nautilus crept ashore at Makin Island and did what the Raiders were meant to do– hit hard in the most unexpected area they could find and jack up a small Japanese garrison.

While that attack was the pinnacle of U.S. submarine commando ops in WWII, and the Raiders were disbanded by early 1944, the Marines did not forget the concept of amphibious scouts and small raiding forces carried by submarines when the war was over.

Scouts and Raiders Painting, Oil on Canvas; by Carlos Lopez; C. 1943; Framed Dimensions 29H X 44W Accession #: 88-159-HD as a Gift of Abbott Laboratories “Commandos of the Navy, they leave a transport, submarine, or invasion craft in their black rubber boats at night on reconnaissance, scout, or demolition missions against enemy-held shores. Their faces and hands painted black for night operations, and now called officially Amphibious Scouts by the Navy, they specialize in rugged finesse. Here they go up and over some rock jetties.”

In 1948, the Marines pushed to convert a dozen Balao-class fleet subs into auxiliary Submarine Troop Carriers (ASSPs) which would involve removing all the torpedo tubes (the Navy loved that idea) as well as two of the big main diesels and using the new-found space to install extra bunks, showers and a pressure-proof hangar mounted outside of the pressure hull on deck. These subs would be able to carry 120 troops including an LVT with a jeep and equipment stowed aboard and eight rubber raiding rafts.

The vehicle could be carried in the cargo hangar and launched by flooding down the submarine. USN photo and text from The American Submarine by Norman Polmar, courtesy of Robert Hurst.

In theory, these boats could lift an entire reinforced battalion landing team with four 75mm Pack Howitzers, six 57mm recoilless rifles, 12 jeeps, 12 LVTs, 48 boats, 220 tons of ammo and ordnance; and 158 tons of supplies– enough to operate for ashore for ten days.

The bad news for the USMC was that the Navy just converted two of the subs– USS Perch (SS-313) and USS Sealion (SS-315). While they were later used extensively to support the Navy’s own UDT operations through the Vietnamese conflict, they didn’t come close to realizing the Marine’s vision in 1948.

Nonetheless, the Marines continued to trial submarine operations with smaller teams of amphibious recon troops in the 1950s, as seen in these great images:

The submarine above is USS Greenfish (SS-351). Greenfish was a Balao-class fleet sub commissioned 7 June 1946, too late for WWII. She did, however, perform duty during the Korean and Vietnam wars and, after she was decommissioned in 1973, was transferred to the Brazilian Navy as the submarine Amazonas (S-16), who kept her in service for another 20 years before she was ultimately scrapped in 2001. In U.S. service, Greenfish sank two submarines in her career, the captured U-234 in 1947 and her sister ship and former Warship Wednesday alumni USS Barbero (SS/SSA/SSG-317) off Pearl Harbor, Hawaii, on 7 October 1964 after that ship was stricken.

The tradition of the Raiders and their use from submarines continues in the modern-day Raiders, recon teams, and, of course, Navy SEAL units who utilize several dedicated boats including the Seawolf and modified Ohio-class SSGNs when they are feeling particularly froggy as well as the organic Combat Rubber Raiding Craft companies built into to each of the seven Marine Expeditionary Forces.
